I ended up having a lot of grandparents. Like a lot. 11 of them. The result was a lot of grandparent nicknames.
My mom's mom: Nanny (pronounced non-e)
My mom's dad: Grandpa
My mom's stepmom: Vi (her first name. They didn't get married until my mom was about my age now.)
My father's mom: Grandma
My father's stepdad: Bill
My father's dad: Grandpa Forrest (yes, his real name is Forrest)
My father's stepmom: Granny
My stepdad's mom: Ba-Chan (Japanese for grandma)
My stepdad's dad: Dad's dad (he died before my mom met my stepdad)
My stepmom's mom: Grandma F*
My stepmom's dad: Grandpa F*
The Bear and The Monkey have 6 grandparents none of which are Grandma or Grandpa. Nanny & Poppy, Grammy & PaPaw and Papa & Nana.
What do you have? What do you envision yourself being called once you reach that stage in life?
